is it possible to balance 2 discs?
 

I always use Shrink to backup DVD movies. :)
now I have a set of movie which has 2 discs (7G + 3G).
if I use normal procedure, I have to shrink alot on disc 1 to fit onto one 4.7G disc, and leave much space on disc 2.
so wonder if it's possible to move some files from disc 1 onto disc 2, so both discs can have about 5G size. therefore, only need to shrink bit of both to fit onto 2 discs evenly.
have tried to move 1 file from disc 1 folder to disc 2 folder.
but Shrink says can't find last file on disc 1 folder, and doesn't read the moved file on disc 2 folder.
so anyone has solution on this?
tks, folks.
